# WebSocketBase 

###
Companion object WebSocketBase

#### trait WebSocketBase extends ReadStream[Buffer] with WriteStream[Buffer]

Base WebSocket implementation.

It implements both and so it can be used with io.vertx.scala.core.streams.Pump to pump data with flow control.

### Abstract Value Members

1.  abstract def asJava: AnyRef
   Definition Classes
     WebSocketBase → WriteStream → ReadStream → StreamBase
2.  abstract def binaryHandlerID(): String

   When a `Websocket` is created it automatically registers an event handler with the event bus - the ID of that handler is given by this method.

   When a `Websocket` is created it automatically registers an event handler with the event bus - the ID of that handler is given by this method.

   Given this ID, a different event loop can send a binary frame to that event handler using the event bus and that buffer will be received by this instance in its own event loop and written to the underlying connection. This allows you to write data to other WebSockets which are owned by different event loops.

   returns

     the binary handler id

3.  abstract def binaryMessageHandler(handler: Handler[Buffer]): WebSocketBase

   Set a binary message handler on the connection.

   Set a binary message handler on the connection. This handler serves a similar purpose to io.vertx.scala.core.http.WebSocketBase#handler except that if a message comes into the socket in multiple frames, the data from the frames will be aggregated into a single buffer before calling the handler (using io.vertx.scala.core.http.WebSocketFrame#isFinal to find the boundaries).

   handler

     the handler

   returns

     a reference to this, so the API can be used fluently

4.  abstract def close(): Unit

   Close the WebSocket.

5.  abstract def closeHandler(handler: Handler[Unit]): WebSocketBase

   Set a close handler.

   Set a close handler. This will be called when the WebSocket is closed.

   handler

     the handler

   returns

     a reference to this, so the API can be used fluently

6.  abstract def drainHandler(handler: Handler[Unit]): WebSocketBase

   Set a drain handler on the stream.

   Set a drain handler on the stream. If the write queue is full, then the handler will be called when the write queue is ready to accept buffers again. See io.vertx.scala.core.streams.Pump for an example of this being used.

   The stream implementation defines when the drain handler, for example it could be when the queue size has been reduced to `maxSize / 2`.

9.  abstract def endHandler(endHandler: Handler[Unit]): WebSocketBase

   Set an end handler. Once the stream has ended, and there is no more data to be read, this handler will be called.

   returns

11.  abstract def frameHandler(handler: Handler[WebSocketFrame]): WebSocketBase

    Set a frame handler on the connection.

    Set a frame handler on the connection. This handler will be called when frames are read on the connection.

    handler

      the handler

    returns

      a reference to this, so the API can be used fluently

12.  abstract def handler(handler: Handler[Buffer]): WebSocketBase

    Set a data handler.

    Set a data handler. As data is read, the handler will be called with the data.

    returns

      a reference to this, so the API can be used fluently

    Definition Classes
      WebSocketBase → ReadStream
13.  abstract def localAddress(): SocketAddress

    returns

      the local address for this socket

14.  abstract def pause(): WebSocketBase

    Pause the `ReadSupport`.

    Pause the `ReadSupport`. While it's paused, no data will be sent to the `dataHandler`

    returns

      a reference to this, so the API can be used fluently

    Definition Classes
      WebSocketBase → ReadStream
15.  abstract def remoteAddress(): SocketAddress

    returns

      the remote address for this socket

16.  abstract def resume(): WebSocketBase

    Resume reading.

    Resume reading. If the `ReadSupport` has been paused, reading will recommence on it.

    returns

      a reference to this, so the API can be used fluently

    Definition Classes
      WebSocketBase → ReadStream
17.  abstract def setWriteQueueMaxSize(maxSize: Int): WebSocketBase

    Set the maximum size of the write queue to `maxSize`.

    Set the maximum size of the write queue to `maxSize`. You will still be able to write to the stream even if there is more than `maxSize` items in the write queue. This is used as an indicator by classes such as `Pump` to provide flow control.

    The value is defined by the implementation of the stream, e.g in bytes for a io.vertx.scala.core.net.NetSocket, the number of io.vertx.scala.core.eventbus.Message for a io.vertx.scala.core.eventbus.MessageProducer, etc...

    maxSize

      the max size of the write stream

    returns

      a reference to this, so the API can be used fluently

    Definition Classes

18.  abstract def textHandlerID(): String

    When a `Websocket` is created it automatically registers an event handler with the eventbus, the ID of that handler is given by `textHandlerID`.

    When a `Websocket` is created it automatically registers an event handler with the eventbus, the ID of that handler is given by `textHandlerID`.

    Given this ID, a different event loop can send a text frame to that event handler using the event bus and that buffer will be received by this instance in its own event loop and written to the underlying connection. This allows you to write data to other WebSockets which are owned by different event loops.

19.  abstract def textMessageHandler(handler: Handler[String]): WebSocketBase

    Set a text message handler on the connection.

    Set a text message handler on the connection. This handler will be called similar to the , but the buffer will be converted to a String first

      a reference to this, so the API can be used fluently

20.  abstract def write(data: Buffer): WebSocketBase

    Write some data to the stream.

    Write some data to the stream. The data is put on an internal write queue, and the write actually happens asynchronously. To avoid running out of memory by putting too much on the write queue, check the io.vertx.scala.core.streams.WriteStream#writeQueueFull method before writing. This is done automatically if using a io.vertx.scala.core.streams.Pump.

    data

      the data to write
